How do I use "Album Sort" and "Album Artist Sort" meta data in Naming the files?

I've tried with:
[IFVALUE]album artist sort,[album artist sort],[IFVALUE]album artist,[album artist],[IFCOMP]Various Artists[][IF!COMP][artist][][]\[album]\[IFMULTI][disc]_[][track] [artist] - [title].[cddb_id]

But it seems that "Album Artist Sort" is not recognized as a valid meta tag.
